UNI-Ten STATES STEPHEN woon MC'CLAVE, XJR., nosooE PARK MCCLAVE, AND BERNARD DUNCAN MccLAVE, or cnirrsrnn, New .nnsmc SEWER BOAT.

Application filed February This invention relates to a sewer boat.

in the smaller municipalities the sewers are laid andA supervised by engineers that inl-many cases eniployedonly temporarily by the municipality and their recordsbeing private records arcnot preserved by the municipality. in'otlier cases the records arernot properly looked after, becomelost or are destroyed by rc. if sewer has been laid and the maps and plans are not available it is impossible to determine vwhere the Y `outlets or connections are located. 1f a property'owner desires to connect up with the sewer it is of prime importance that his connection be made to a Y since,.if it is not rdone it impossible to make a tight joint inthe sewer seepage results around where .the senfer pipe has been cut out for the entering pipe. In order therefore notto cut the sewer pipe, excavation may be necessary for a considerable distance in order to. locate the Y which entails unnecessary expense and where there is rock it entails a heavy charge upon the house builder. Y

One of the objects of thisinvention Vis to provide a device which will indicate the Y outlets of a sewer. Another object of this invention is to indicatethe'direction as well as the location of Vsewer outlets. y Still another obj'ect of the invention is to enable the determination of any openingor break in a pipe.

Referring to the drawings:

Figure 1 is a plan View of a device embodying' the principles of my invention being drawn through a sewer.

Figure 2 is a side view elevation of Figure 1.

Figure 3 is a plan view of a modified form of my invention.

Figure 4 is a diagrammatic view of the electrical wiring.

1n carrying out our invention, I propose to provide a sled or boat 1 having runners or sides 2 and deck 3. Forward of mid-secn tion I provide rotatable arms, 4, 4' and 4". Said arms 4, 4' and 4" have pivotal mountings 5, 5 and 5" to deck 8. The arms 4, 4', being rotatable in the horizontal plane and arm 4 in the vertical plane.l Stops 6, 6 and 6 limit the throw of the arms. Springs 7, 7 and 7" are secured to deck 3 forward of the arms 4, 4', 4 respectively, and also to the arms in order to rotate the arms forward,

when pressure against the tips of the arms is sewer pipe and` 9, 1925. Serial N0. 7,761.

released, .to bring-contacts 8,v 8 and 8" carried at thebasethereof into electricalcontact with contact @secured to deck 3. Wires 10, 10 yand 10" Vare connected to contacts v8,l

8 and 8" and with wire 11 connected to contact V9, which are lthe four wires of a four stranded cable. 12and which Vpass down.l through opening 13 in deck Sand-are then-v secured to the stern of the boat from whence it extends.' A tow rope 14 is secured to'boatl 1 Vin such a fashion as to pullthe boat horizontally without hlifting the prow and this is accomplished-by passing a rope throu h openings 15, 15 -in deck 3 on each side of t e center line thereof'to the underside offdeck 3 and ythen through openings 16, 16.V of the sides or runners Vand back through openings 17,17' to the underside of the deck, said openfings being 'adjacent the mid-section and thenceto-the rear where said tow rope is seured to the underside ,ofv thevsterny of. the

Cable 12 containing wires 10, 10, 10 and l1l lead to bells V18, 18Jand 18"and to batteries 197 to form a circuit or circuits andto ring the bell orbells when the contacts carried by the arms 4, 4", 4"and 9 are closed.

.The modified form of device is similarlto the preferred embodiment except that the arms 4, 4', 4 whenl rotated operate by means of levers 19, 19', 19, to sound mechanical Y bells 20, 20' and 20" secured to deck 3.

TheY operation of the device is as follows:

i The tow rope 14 is passeddown through the sewer in which it is desired to ascertain where the Y connections are. then inserted in the sewer 21and towed through the section which it is desired to be explored. The arms 4, 4', 4" are held back from the contacts 8, 8,8" and 9 by the walls of sewer 21, while the vboat is towed.` A Y connection being reached, the arm opposite the Y connection is swung back by the spring that is attached thereto causing its contact to complete the circuit and ring its particular bell. As the'bells are of different sizes and tonal qualities it can be immediately determined from the sound which arm or arms 'have located outlets or it may indicate breaks in the pipe line. Two bells ringing indicate The boat is a Y connection or outlet; one bell ringing ins dicates a break.

generally moresatisfactory yet under certain conditionsr it may be desirable to ldis-y pense with the electrical features.` The sound of a bell can be heard for a very long distance when it is vrung` in a sewer pipe. The modified form ismanipulated in the same manner, the only difference being,- that the arms themselves strike against a bell through a system of levers 19, 19, 19, when` they..

swing out as they come opposite to an opening in the pipe.

Of course modifications may be made in detail such as by making the arms extensible to adapt the boat to a large range of pipe diameters. Other variations may be made in the device and still fall within the scope and f principles of our invention and we do not desire to be limited to itsuse solely in connec (tion with a sewer as the device is extremely feo useful to llocate a break in any pipe of sufficient diameter to permit the device to be use/d.

, What we claim is:

l. An indicator comprising abody portion, said rbody'portion consisting ofa deck and 'side runners. arms pivotally mounted on said pipe, a bellfor each arm and means to actuate the bell when any of said arms rotates Y lbeyond a certain predetermined point in its arc of rotation.

3.V A pipe indicator comprising a body portion consisting of al deck and side runners, arms pivotally mounted on said deck, springs secured to said arms and to said deck forward of said arnisto Vmaintain the* free ends of said'arins in frictional contact with the `wall of the pipe when said indicator has been inserted in the pipe with the arms rotated against the tension of the springs from front torrear, individual bells for each arm and means to actuate each bell when itsarin is rotated beyond a predetermined pointV in its arc'of rotation from rear to front.V

ll. A pipe indicator comprising a body portion consistingof a deck and side runners, l

an arm pivotally mounted on said deckand rear to front of said deck portion and sidewise thereof, springs secured to said arms `adapted to swing from rear to front along vthe longitudinal axis of said deck, arms piv- V otallyl mountedy on said deck on each side of ysaid central arm 'and adapted to swing from and to said deck to maintain the free ends'` of `said arms in frictional contact with the in- `terior of the pipe wall ,'individua'l bells for each of said arms, a oontact'member carried by said deck, contacts at the pivoted 'i ends ofsaid arms to engage said contact member carried by the deck when any of said arms has moved beyond ya certain predetermined point in its arc ofrotation from rear to front, wires connecting` said contacts with the said individual bells and a source of Y electrical supply.
